Hot-rolled steel sheets and strip products are made of slabs (mainly continuous casting billets), which are heated to form strips from roughing mills and finishing mills. The hot steel strip from the last rolling mill of the finishing mill is cooled to a set temperature by laminar flow, rolled into a steel coil by a coiler, and the cooled steel coil is subjected to different finishing operations according to different needs of users. Lines (flat, straight, cross-cut or slit, inspection, weighing, packaging and marking) are processed into steel, flat and slit steel strips. Because hot-rolled steel sheet products have high strength, good toughness, easy processing and good weldability, they are widely used in ship, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries. With the increasing maturity of new technologies such as hot-rolling dimensional accuracy, plate shape and surface quality, and the advent of new products, hot-rolled steel sheets and strip products have become more and more widely used and are becoming more and more powerful in the market. Competitiveness. Generally speaking, hot-rolled steel products have a wide variety of specifications and applications. From general engineering structures to automobiles, bridges, ships, boilers and pressure vessels, they are widely used. For various purposes, the requirements for the material properties, surface quality, size and shape accuracy of the steel sheet are also different. Therefore, it is necessary to understand the varieties, materials, characteristics and uses of the hot-rolled steel sheet products in order to achieve economical efficiency. Reasonable use.
